We're writing an article on the largest Craft sites built and I'm having some challenges finding this information. Ideally, we want to compile a list of the top 20. "Largest" is determined by certain criteria like: Traffic (uniques/month; and pages/month); Number of Entries, Number of Members; Number of forum posts, etc.
I came across this article https://straightupcraft.com/articles/who-uses-craft-cms as a start to find out some basic info on sites built in Craft but it doesn't provide me with any info that would suggest these are some of the largest sites. In fact, when I entered in some of the names from that list into Alexa https://www.alexa.com/siteinfo their global ranking was quite low. I'm seeking help on how to surface this info.
